LIGHTING-FIXTURE.

Specification of Letters Patent.

' Patented Julie 27, 1916.

Application filed January as, 1915. Serial a... 4,815.

To all whom it may concern: I

Be it known that I, HARRISON D. MoFAD- DIN, a citizen of the United States, residing in the city of East Orange, county of Essex, and State of New Jersey, have invented a certain new and useful Lighting-Fixture, of which the following is a specification.

This invention is a lighting fixture of a character particularly adapted for use in member being preferably retained in its op- V erative gripping position by the means which supports the shade on the fixture.

It will be noted that thedevice is exceptionally simple and economical to manufacture.

In the preferred practical embodiment of the invention, an annular member is provided, adapted to-engage withthe usual peripheral flange on the shade or globe, and to this annular member are secured a plurality j of supporting elements adapted to engage with attaching devices on the fixture for supporting the globe beneath, and in proper relation to, the source of light.

A salient feature of the invention resides in the fact that one of the supporting ele ments cooperates with the annular member in such manner as to lock the same in-clamping position upon the globe, and suchelement is adapted to be manipulated to unlock the annular-member toiallow of the removal of the globe from the fixture.

Features of the invention, other than those specified, will be apparent from the following specification read in conjunction with the accompanying drawings.

In the accompanying drawings, I have illustrated one practical 'embodimentof the present invention, but the construction shown therein is to be understood as illustrative, only, and not as defining the limits of the invention.

Figure 1 is a side elevation 'of a lamp fixture embodying the present invention, the parts thereof being shown in their operative positions. Fig. 2 is .a similar viewrof the fixture, with the globe tilted to allow of cleaning the interior thereof. Fig. 3 is a fragmental section taken on line 33 of Fig. 1, Fig. 4 is a fragmental, plan view of the annular member with the globe detached, said annular member beingshown in its closed and locked position, and Fig. 5 is .a view similar to Fig. 4, with the free ends of the annular memberunlocked and parted .to allow of the removal or replacement of y the globe.

Referring to said drawings, A indicates a fixture of any common and well-known type, provided with a socket a, into which is adapted to be screwed the plug of an electric bulb B. The fixture is, moreover, provided a with a plurality of globe-supporting devices,

shown in the drawings as three hooks c, which are stationary with the fixture. These hooks serve as the primary carrying elements of the globe.

The globe is designated by the reference numeral D, and, while shown semi-spherical in shape, .may be of anyshape or contour desired. Globe D is provided at its upper edge with the usual laterally extending, peripheral flange d, by which it is adapted to be supported.

According to the present invention, an annular member E is provided, which is adapted to engage with the peripheral flange d of the globe, and this annular member w ring is preferably of metal, its function being when in engagement with flange (Z, to provide means whereby suitable supporting devices may be employed to sustain the weight of the globe. In the preferred embodiment of thevinvention shown, ring E is channeled in cross-section and is parted at one sideto allow it to be positioned on, or removed from, globe: D. Its free ends are adapted to overlap one another when the ring-is in contracted operative position in engagement with the globe, and means is provided for locking these ends in overlapped relation. Ring E is supported in relative ,position'to the vfixture and below the lamp by means of a plurality of chains,

links, or barsc, the upper ends of which are provided with eyes adapted to engage with the hooks c, and the lower ends of which are provided with hooke 6 adapted to be passed through apertures f in the upper portion of the channeled ring E. Links 6 thus serve as a support for ring E and the globe embracedthereby. It will be noted, from Fig. 1, that two apertures f are positioned near the free ends of the ring and are of such distance therefrom that, when the free ends of the rings are overlapped, these two apertures will come into alinement. If the hook c of one of the links 6 is. passed through said alined apertures, when the ends of ring E are in overlapped relation, this hook will serve to lock the parts together after the manner clearly shown in Fig. 3. The remaining apertures f are spaced at proper distances around the ring E, and with each of these apertures cooperates a link '6.

It will thus be manifest that, of the several links which operate to support the globe, one of them serves a dual purpose, viz., it supports the globe and simultaneously locks the ring E in its clamped or closed position. This obviates the necessity of independent fastening devices and makes the fixture of the present invention extremely simple, yet, withal, highly efficient. By virtue of the simple manner in which the links are secured tofixture A, they may be readily detached therefrom by simply loosening their upper ends from their respective hooks 0. However, when it is desired to clean'the interior of the globe, it is only necessaryto loosen one of the links a, whereupon the portion of the globe supported by said link will sag or drop and thereby cause the globe to tilt into the position shown in Fig. 2, while the same is supported on the remaining links 6. When in the position shown in Fig. 2, access may be readily had to the interior of the globe without detaching the same from the fixture and, when the cleaning operation is finished, the globe may be restored to its initial, normal position by simply rehooking the upper end of the link 6 over its corresponding hook 0.

As heretofore stated, ring E is preferably channeled in cross-section, and this insures against the inadvertent falling forward of the globe, when in the position illustrated in Fig. 2, should said globe tilt to a greater angle than that shown, it being manifest that, when the locking link is in place, ring E serves as abinding for the upper portion of the globe and is lockedthereon against removal in any direction until the link in question is removed from the aperture lVhen it is desired to remove globe D from ring E, the link a, which engages with the alined apertures f, is detached from the hook 0 of the fixture and is swung outwardly into substantial alinement with the top ed e of the globe, whereupon the shifting of said link toward the center of the globe, as shown in dotted lines in Fig. 3, will cause the hooked end 6' of said linkto become disengaged from ring E, with the result that the ends of said ring are unlocked and are allowed to part, as shown in Fi 5. The globe may now be removed. In replacing the globe, the reverse of the foregoing operation is carried out.

It will be manifest, from the foregoing description, that the device of the present invention is extremely simple, yet absolutely positive in its operation. The globe, when locked to ring E, cannot become detached and fall out, either in its normally closed position or in its position for cleaning. This is an important feature, from the standpoint of the user.

The separate elements which combine to make up the combination are, in themselves, simple and very economical to manufacture, all milling, threading, and other expensive mechanical operations being dispensed with, and these elements are of such construction that nothing can possibly get out of order, even through a long period of use.

I have described and shown the preferred embodiment of the invention, although it will be manifest that slight changes may be made, from time to time, in adapting the invention to various typesof fixtures, either gas or electric. Moreover, ring E may be decorated or formed in artistic manners, and may, if desired, be of other than channeled cross-section, such, 6. g., as L-shaped. Furthermore, if a polygonal-shaped globe is desired, it will, of course, be understood that ring E will be made of corresponding shape.

in contour. I, therefore, wish it understood that I do not restrict the present invention to the precise structure described and shown, but consider my invention as broadly new as commensurate with the appended claims.

It will be noted that, in the construction described, it is not necessary to drill or perforate the globe, as is the case with many of the supporting devices now employed. Moreover, the supporting ring and wire links not only avoid excessive shadows, but reduce the shadow effects to a minimum.

Having thus fully described the invention, what I claim as new, and desire to secure by Letters Patent, is 2- 1. In a device of the class described, means for gripping a lamp globe, and a supportlng member formed at one end with means for engaging a fixed support and at its other end with means for securing the gripping member on the globe, whereby said supporting member maintains the globe and its gripping member in operative relation and simultaneously supports the globe and gripping member.
